Esso 20min sd color loan 541.2 sh-c-ad How atoms of carbon, hydrogen and oxygen in various combinations go together to form such seemingly unrelated products as coal, petroleum, starch, sugar and rubber. Animation is used to explain the principles CATALYSIS. BBF 1937 llmin sd (Chemistry ser) ?45. rent $2 541.2 Jh-sh-c Guide Collaborators: Hermann I. Schlessinger and Warren C. Johnson, University of Chicago Presents explanations of several phenomena associated with catalysis, among them, concentration by absorption, activation by absorption, intermediate compounds. In a homogeneous mixture, chain reactions, braking of reaction chains, poisoning of catalysis, and negative catalysts or inhibitors. The practical applications used as a basis for explanations are rubber manufacturing and anti-knock gasoline THE ELECTRON.

Lemon, University of Chicago By means of various photographic techniques including animation, the hypothesis that electricity consists of unit elementary charges is supported by observation of phenomena associated with the conduction electricity ,ln liquids, gases, and vacuums. The conclusion drawn Is that the fundamental unit of an electrical charge is the electron INSIDE THE ATOM.

Lemon of the University of Chicago Evidence of molecular activity in gases, liquids, and solids is presented in support of the molecular theory of matter. Animated drawings explain such phenomena as the diffusion of gases, the evaporation of liquids, and the transformation of liquids into solids, In terms of the theory. Among the features of the film are the machine gun illustration of the force exerted by moleeules in motion, and the microscopic view of the Brownlan movement ONE WORLD— OR NONE. FlmPub or Assn Flm 1946 9min sd $30, rent $2 541.2 Jh-sh-c-tr-ad-forum Guide Produced in cooperation with the National Committee on Atomic Information On atomic power, with vividly graphic animated drawings and live-action scenes. Five factual concepts are developed: there is no secret — atomic energry was discovered through the combined efforts of scientists of many nations; the destruction at Hiroshima Is compared with that which would result in major cities of the world; the deadly effectiveness of the atom bomb is compared with that of other weapons of the past; the vulnerableness of any nation is emphasized; and that there is no effective defense is proven graphically. Therefore, the people of the world must learn to live together Filmstrip of the same title is listed in the 1948 Annual Filmstrip Guide "Here is a forceful film, cleverly handled in its animated drawings, backed up by Raymond Swing's narration, effectively pointed music. It is suitable for all school and outside groups, not as a technical explanation of the atomic process but rather as a discusslonaJ lever."

Arey, University of Alabama The Aim concerns itself principally with the three essentials of combustion — fuel, oxygen and a kindling temperature which depends upon the kind of fuel involved. Animated drawings illustrate these principles.
